I think the caller is only trying to see if your home,there not selling anything,and have nothing to do with warrantys. You can call the cops but they are the cops!! Or used by them. They have been calling me for years,no real businesses could afford to waste their time,except people working for the government. The government is like the Catholic Church,they never get rid of there perverts,just send them to Idaho.
Are you home,they pretend to sell warranty,all a lie!! Losers working for the government,if they don't do this they will be back in a homeless shelter. Wait until they get old enough for retirement
